I am working on a small private project and I miss some basic knowledge about condensatoir.My question will be very basic, but that issue put me into doubt

I have a schematic and I can see diffrent symbol of condensator.I am also working with Fritzing which is an opensource PBC maker. In order to not make error on componment I would like to ask you the difference between some condensator

Could you open the fisrt pdf file http://www.hello-web.net/temp/PowerCell.pdf and look at C1, C2 and C3. All have a different representation.Also, is it true that the Output pin of U2 (VCC) has to be "wired" to the the Resistor R2 (VCC) in my PBC?

Could you also check the second file http://www.hello-web.net/temp/Pro-Mini.pdf and look at C19, C10 and C2. And what is the element between pin 7 and 8??I suppose that C19 has a polariry and why C10 has a smaller bar.

With Fritzing, I can select a condensator which show a voltage. Why voltage are not show in the linked shematic?

Capacitors have a rated voltage. You should select a capacitor with a voltage rated higher than the voltages it will see in the circuit. Knowing this, there isn't much need for calling out a rated voltage on those simple schematics.

Ok, good, thank for that information.May I ask you again one thing?On that file http://www.hello-web.net/temp/PowerCell.pdf what is JP9. Could it be two hole where I can solder a 5V and GND wires to charge the battery (IN).

What is the difference between JP1 and JP12. I suppose the battery will be plugged here, but in which one?

HelloThank for all information and excuse me for my misspelling (PCB, capacitor).

Ok then I can consider JP12 and "delete" JP1. I would like to have a JST connector with a Li-ion battery always plug. When I plug the USB cable it's charging and power my project. When I remove the USB, the battery power my project.

I just discover something else. I can read GND and GND1. GND should be the GND of my Li-ion, but then GND1?

The reason for two grounds is because you are using a switching regulator. The chip separates "logic" and "power" ground. You should be putting a ground plane underneath the TPS chip. All of the "GND" connections on both schematics need to be connected to that plane. All of the GND1 connections are "logic" should be connected together, then with a single point to the GND.

Some of this is explained on page 13 of the TPS datasheet:http://www.ti.com/lit/ds/symlink/tps61200.pdf
